SPECIFICATION forming part of Letters Patent No. 477,544, dated June 21,18920 Application filed April 14, 1891 Serial No. 388,840. (No model.)

. HARVEY F. TURNER, both of Oakley, in the county of Logan and State ofKansas, have invented a new and Improved find-Motor,

of which the following is a full, clear, and 6X1 act description.

The object of the invention is to provide a new and improved wind-motorwhich is simple and durable in construction, very effective and powerfulin operation, and arranged to transmit the force of a series ofwind-wheels to a common shaft.

The invention consists of certain parts and details and combinations ofthe same, as will be hereinafter fully described, and then pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

- Figure l is a side elevation of theimprovement with parts in section.Fig. 2 is a sectional plan view of the same on the line a: a: of Fig. 1.Fig. 3 is an inverted plan view of the turn-table, and Fig. 4 is a planview of the bearing for the turn-table.

The improved wind-motor is provided with a suitably-constructed tower A,provided with posts B, set in the ground and inclined toward each other,as is plainly illustrated in Fig.1. The posts B are connected with eachother near the ground by braces O, and the upper ends of the said postsare engaged by ears D, formed on the under side of a bearing-plate D,provided on its top with an annular offset D fitting in to acorrespondingannular recess E, formed in the under side of the turntableE, as is plainly shown in Fig. 1.

On the periphery of the turn-table E are formed ears or lu s E en a inosts F of a D 9 b b D frame G, mounted to revolve on the outside of thetower A. The upper ends of the posts F of the frame G are connected witheach other by a plate F, and the lower ends of the said posts carry aring F mounted to turn on its inside on friction-rollers 0, arranged ina circle and supported on the braces C of the tower A. (See Fig. 2.)

In the center of the plate F and in the center of the turn-table E ismounted a shaft H, which extends vertically in the center of the towerA. The lower end of the shaft H is set in a suitable step I, and nearthis lower end of the shaft is secured a bevel gear-wheel l1, meshinginto a bevel gear-wheel J, secured on a main driving-shaft J, mounted toturn in suitable bearings on the tower and carrying at its outer end abelt or crank-wheel J for transmitting the motion of the maindriving'shaft to other machinery. On the upper end of the shaft H, abovethe plate F, is seen red abevel gear-Wheel H meshing into a bevelgear-wheel K, secured on a shaft K, mounted to turn in suitable bearingson the plate F and carrying at one outer end a wind wheel K -On theshaft II, above the turntable E, is secured a bevel gear-wheel 1-1meshing at opposite sides into bevel gearwheels L and N, secured at theinner ends of shafts L and N, respectively mounted to turn in suitablebearings on the frame G. On the outer ends of the shafts L and N aresecured the bevel gear-wheels L and N respectively in mesh with thebevel gear-wheels L and N respectively secured on the upper ends of theshafts L and N respectivelymounted to turn in suitable bearings securedonto oppositely-arranged posts F of the frame G. On the shafts L and Nare secured the bevel gear-wheels L and N respectively in mesh with thebevel gear-wheels O and P, respectively secured on shafts O and P",respectively mounted to turn in suitable bearings'arranged on the postsof the frame G and extending horizontally parallel with the shaft K,previously mentioned. On the shafts O and P are secured the wind-wheelsO and P respectively, similar to the wind-wheel K and extending in thesame direction. On the lower ends of the shafts L and N are secured thebevel gear-wheels L and N respectively in mesh with the bevelgear-wheels Q and R, respectively secured on the shafts Q and B,respectively mounted to turn in suitable bearings on the posts of theframe G and extending horizontally parallel to the shafts O P K. On theshafts Q and R are secured the wind-wheels Q and R presenting the sameface to the wind as the wind-wheels O P K previously mentioned.

On the revolving frame G is arranged a suitable vane S, (shown partly indotted lines in Fig. 2,) so that the said frame is turned into theproper position to present the wind- Wheels K O P Q R to the wind.

The operation is as follows: The wind act ing on the vane S revolves theframe G on the tower A, so that the faces of the wind-wheels are actedon by the wind, whereby the windwheels are turned and by theirconnection With the shaft Ilimpart a powerful rotary motion to thelatter. The shaft H, by being geared with the main'driving-shaft J,imparts a rotary motion to the latter, so that the heavy machinery canbe actuated by suitable means from the said shaft J. It will thus beseen that the combined force of the several wind-wheels is transmittedto the main driving-shaft, and consequently to the machinery to bedriven.

Having thus fully described our invention, we claim as new and desire tosecure by Letters Patent- 1. A windmill comprising a tower, a verticalcentral shaft therein, a turn-table on the top of the towerand connectedwith said shaft, a rotary frame depending from the turn-table andinclosing the tower, the frame having a ring on its lower end travelingabout a circular track on the lower portion of the tower, upper andlower horizontal wind-wheel shafts journaled on said rotary frame, andverticallyextending shafts geared to the horizontal shafts and in turngeared to the central vertical shaft, substantially as set forth.

2. A windmill consisting in a tower A, formed of posts B, connected attheir upper converging ends by the plate D, a rotary frame G, inclosingthe tower and having a turn-table near its upper end turning on plate D,a plate F on top of the frame G, a ring F on the lower end of the frameG, a circular track on the lower part of the tower for said ring andformed of anti-friction rollers 0', central vertical shaft H, extendingdown through plate F and the turn-table to the bottom of the tower, anupper windwheel shaft geared to shaft H, horizontal wind-Wheel shafts onthe rotary frame, and vertically-extending shafts L N, connecting saidhorizontal shafts and geared to the shaft H between the turn-table andplate F, substantially as set forth.
